hey all -
Hopefully this is a fairly easy question. I’m about to put in a CSF 2888 brass replacement radiator. I’m not a fan of the plastic drain plug wing nut.
It looks like the drain hole is threaded in the brass - but I can’t figure out what the threads are. It’s roughly 3/8 but the threads are larger (coarser) than 3/8 NPT. I’m guessing it’s a coarse M10 thread - maybe M10 1.5 or M10 1.25?
I’d like to build a tube extension like the OEM radiator had to get the drain point below the radiator cradle for easy access.
Has anyone been down this road? Worst case I’ll go buy an assortment of brass plugs and test fitting but metric plugs aren’t super available around here.
